To all whom it may concern.-

Be it known that I, ALFoNs MAUSER, a citizen of the German Empire, residing at Cologne, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in and Connected with Casks, Barrels, Drums, and the Like, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

This invention has for its object a sheetmetal cask, barrel, or drum tapering toward both ends in such a way that grooves gradually becoming dee er toward both ends are formed in a suita le manner in the sheet metal casin which is at first made cylindrical, and t us the casing is caused to taper without waste of material while simultaneously increasin the strength of the cask, barrel, or drum. lhe ends of the cask or barrel are flan ed or swaged onto the casin for which 0 ject the corrugated casing e ge is first ressed fiat and then flanged. The ends are tiien flanged round this edge of the casing, if desired, a washer-band being inserted between them. If it is in some circumstances desired that one end of the cask be removable, thus formin a sort of lid, a separate ring attached to the casing is introduced between the cask-casin and the end, in the a groove of which ring t e lid which is provided with an edge all round is inserted, a Washer being placed between and fixed thereto by means of revoluble bolts. The center part of the cask, barrel, or drum is suitably strengthened-for instance, by impressing a number of circular grooves or by lacing thereon separate means of stren tiiening, such as hoops, rings, or the like. e sheet metal casing may also, if desired, be made in three parts and a thicker plate employed for the center part. The separate parts of the casing and also the bottoms may. be tightly connected with one another by folds or corrugati'ons. It ma also be referable to make the cask p0 ygonal in t e-middle instead of circular, in such a way that when lying on its side it cannot roll away, but will remain stationary, with its prismatic surfaces on the ground.

The cask or barrel may be of any suitable section, but usually a circular one is preferable. However, in order to save spacefor instance, for export purposes-a rectangular section may also be adopted.

The object of the invention is shown as an example in the accompanying drawings.

Fi ure 1 is a longitudinal section of a sheetmeta barrel, cask, or drum; Fig. 2, an elevation of a circular sheet-metal cask or barrel, the middle part of which is prismatic in form; Fig. 3, a plan view of the sheet-metal cask, showing the bottom ofsame; Fig. 4, a

lan view of a sheet-metal cask in which the bottom is removable; Fig. 5, a cross-section of the end of a cask with a removable bottom. Figs. 6 to 14 are on an enlar ed scale and represent, in Fi s. 6 to 9, means or connecting the parts of t e cask and in Figs. 10 to 14 means for strengthening the middle part of the cask.

If the cask or barrel be intended to receive liquids, it may be provided witha bung-hole y, as shown in Fi 2.

The sheet-met l casing a of the cask or barrel, which casing is first made cylindrical or rismatic and is closed b means of a seam I 1s tapered toward both ends by grooves b, increasing in depth from the mi d e toward the ends, being impressed or formed therein. The edges are then pressed smooth for a little farther and flanged or swa ed over a strong 7 wire insertion e or the like, ig. 7.

The cask-bottom c, which may be made concave in any suitable manner,is swa ed, by means of an edge (1, over the edge of t e casing, if desired, a washer-band 9 being inserted where great tightness is required, and in this manner a very solid connection is obtained sufficiently strong to resist the rolling of the cask on its bottom edge. If one end is to be removablethat is to say, if the cask is to have a removable cover or lida .ring is is flanged on the edge of the casin of the cask, which ring has on its inner si e a circular groove 7c, Fig. 6. The lid or cover h is laid in this groove, if desired, a washer-band Z be ing also inserted in such a Way that the edge i of the lid engages in the groove and is drawn into the groove by means of revoluble bolts m engaging under the groove k. If the bolts mare turned laterally, they pass away under the roove k, and the lid may be removed. T e unfastening and fastening of the bolts m take place by means of yokes n, lying over the lid, which yokes are firmly connected with thebolts m by ins 0 pivotal in the lid. This is preferably one by the pins 0 bein rectangular or similarly sha ed in the part w 'ch passes through the lidw 'le other ICC wise being round and the 'yokes n and bolts m fitting firmly on the rectangular part. In order that it may be seen from the outside of a cask Whether the bolts m are secured or open, the yokes n have all a similar direction to the bolts m lying beneath them, and a projection 0 for each of the yokes n is also provided on the lid h, which projections, if sealed to the yokes, prevent any unauthorized turning of the yokes nthat is to say, an unfastening of the revoluble fastening-b0 ts m, Fi s. 4 and 6.

In the case of casks, Figs. 2 and 4, which have a prismatic form in the middle, the casing a is made prismatic at first. After the extending grooves bhave been impressed the corrugated edges are rolled smooth and the round lid or end then attached thereto in the manner hereinbefore described.

If the cask casin be formed of several parts, Figs. 8 and 9, t e center part 1) is made of thicker plate and swaged or flanged onto the side parts a by means of simple folds q or double folds g, according as the cask is required to be more or less water-tight.

The simplest means of strengthening the middle art of the cask is by circular grooves f and which, of course, may also be employed when the cask-casing is formed in several arts, Fi 9. If it is necessary that the middle part of the cask be further strengthened, a separate strengthening-band 'r is placed around the middleof the cask, Fig. 10, which may also be rovided with circular coves, and referalily stands a little away om the cas in order that if the hoo or band be damaged the cask shall not be amaged at the same time. Closed iron rings t, which lie beside the strengthening-ribs f and are connected one with another by means of hoop iron 8, engaging through the rings, Fig. 11, may also be employed as further means for strengthening the cask. 1 The solid or hollow rings tmay, if desired, also lie in a vertical central part a of the cask-casing a and be retained in position by hoo iron .9, both ends of which engage the rings, ig. 12. The caskcasing a ma also be provided in the middle with inward y or outwardly impressed circular grooves z and f, respectively, and the rings may lie in the inwardly-impressed circular rooves z and be connected by hoop-iron 'v, ig. 13, or the rings w may lie directly in the circular grooves 2 without being interconnected.

Of course a large number of methods of stren thening the middlepart of the sheetmetafcask, barrel, or drum may be employed without departing from the scope of the invention. I

All parts of the cask are held together by bending over or swaging, and thus rivets are only necessary when the middle part of the cask, barrel, or drum is strengthened by a hopp or band, Fig. 10.

he cask made in the manner hereinbefore described is of light weight both as compared with sheet-metal drums hitherto employed for similar purposes and also with wood casks of similar content. The cask can also be made considerably cheaper and is particularly suitable for export purposes where great strength of the package with as light a weight as possible is the most essential condition in order to obtain cheap frei ht and lessen custom-house expenses. A rther considerable advantage of this sheetmetal-cask, barrel, or drum tapering to both endsconsists in its convenient handling under transport. These casks may be easily turned on one point and also set up on end with very little trouble. By moving the cask when laid on its side u and down several times a certain oscillation may be produced, and then the cask may be easily set up onend, while in the case of cylindrical sheet-metal casks or drums a considerably greater expenditure of power is necessar that is to say, more ersons are require to handlethe cylindricafiron drums.

The drum, cask, or barrel may be any suitable sectionthat is to say, its form may be round, rectangular, or otherwise-the caskcasin being first made of the desired sectiona form-that is to sa cylindrical or prismatic from sheet meta and then the tapering grooves impressed on both sides.

In cases where it is important to save spacefor instance, in conveyance on board s ip or for storagerectangular casks, for instance, may be preferable to circular ones, as there is less waste space between them than is the case with the latter.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A sheet-metal barrel having a central bilge portion bounded by strengtheningribs, both the bilge and ribs being polygonal, the walls of the barrel from the ribs toward the ends being circular in form.

2. A sheet-metal barrel having at one end an inwardly-extended grooved ring, a re movable head or cover, having a beaded edge seated therein and pivotally-mounted clamping-arms carried by said head and arranged to engage below the ring for locking said head or cover in position.

In testimony whereof I aflix my signature in presence of two witnesses.
